If the Edinburgh International Book Festival wants a way to instil a bit of danger into its programme Mark Watson can provide a template: guerilla book launches don't come any more subversive, claiming the streets for literature and prose, plot and characterisation. A giddy two hour tour of Edinburgh, from New Town to Old, pleasant Pleasance to smelly piss-alley and eventually to a sedate Waterstone's and ringing cash registers.
Enjoy the photos and rue the missed opportunity if you weren't there, but this whole event could have come to a tragic end from a great height if the reading in the alley had gone awry...
